Susan is quite nearsighted; without her glasses, her far point is 34 cm and her near point is 17 cm . Her glasses allow her to view distant objects with her eye relaxed. With her glasses on, what is the closest object on which she can focus?

Answer:


u=34cm

Step-by-step explanation:

From the question we are told that:

Far point is
V=34 cm

Near point is
u=17 cm

Therefore

Focal Length


f=-34cm

Generally the equation for the Lens is mathematically given by


(1)/(u)=(1)/(f)-(1)/(v)


(1)/(u)=(1)/(-34)-(1)/(-17)


u=34cm
